Developmental and Morphogenetic Responses of Mustard Aphid, Lipaphis Erysimi (Kalt) to Methoprene (JHA)

  • Pushpinder J. Rup
  • Rapinder K. Gill


The leaf surface treatment given to nymphal instars of Lipaphis erysimi with methoprene (1–10,000 ppm) prolonged the developmental period only in the second instar. The percentage emergence decreased significantly in the treatments of first and second instar and the alate production increased in the treatment of the latter instar only. In addition, dose-dependent morphological abnormalities were also observed. The longevity and fecundity were affected adversely when adults were given both topical and leaf surface treatments. However, these effects were not transmitted to the F1 generation.

Key Words

Methoprene Lipaphis erysimi development 


Le surface traitement de feuille donnez aux stage nymphes de Lipaphis erysimi avec méthoprene (1–10,000 ppm) a prolongé la période de développement seulement dans la deuxième instar. Le pourcentage d’apparition est démunie significativement dans les traitements de premier et deuxième stage nymphe, et la production de formes ailées a augmenté dans les traitement de deuxième instar seulement. En plus, les abnormalités qui dépendant sur le dose morphologicale ont été aussi observé. La longévité et fécondité ont été affectés contraiement quand on a donné les adultes les deux; le tropicale et le surface traitement. Comme même, les effects nétaient pas transmis au génération F1.
